San Luis Obispo continues to thrive according to the recently released 2012 Gallup-Healthways Well-Being Index Report. San Luis Obispo ranked 10th out of 189 metropolitan areas throughout the US in overall health and wellbeing. The survey assessed: life evaluation, emotional health, physical health, healthy behavior, work environment and basic access to healthcare. In 2008, when SLO ranked 20th overall and first in emotional health, the survey helped author Dan Buettner find San Luis Obispo while researching his National Geographic book “Thrive” leading to him naming SLO the Happiest Town in North America.
